Need help rooting my LG Optimus L70 using TowelRoot

So I'm trying to download towelroot from the website but whenever I go to click that little symbol to download it, it opens up a new page and instead of downloading the apk it just asked a whole page full of life different symbols abd letters and stuff, anyone else have this problem or know anyway around it or to fix it or bypass it or something?? Tried finding an eternal source or download link for it but I couldn't seem to find one anywhere. Any help would be greatly appreciated, and also thanks in advance for any help you can give me.
